/ IMPROVEMENT IN LATE-MILLS.

The Schedule referred to in these Letters Patent and making part of thes ame.

To whom lit may concern:

Be it known that I,`JQHN S. HYDE, ot' Pentwater, in the county ofOceana, and State of Michigan, have invented a new and usefulImprovement in Gang-Lath Mills; and I do declare that the following is atrue and accurate description thereof, reference being had to theaccompanying drawings, and to the letters of reference marked thereon,and heilig a part of this specification.

Figure l is a front view of my apparatus.

Figure 2 is a top View of the same.

The same letters -r'efer to like parts in each figure.

This invention relates to machines for sawing lat-hs, and consists in animproved forni ot' roller, as. will be fully described hereinafter. f

1u order to accomplish this end, I construct a Inachinc, whose variousparts I will now naine.

A is a saw-frame, of any suitable construction, surmouuted by the yokesO, to'ivhich are attached proper arbors for the saw-mandrel D, and theroller-shafts E and F. v

The mandrell) is provided with a gang of saws, secured in the usual wayat or near the outer end of the mandrel.

The saws are designated by x.

The pulley C is fastened upon said mandrel, at or near its centre, andwhen properly connected by a belt, gives motion to the whole of themechanism of the machine. v

0n the. mandrel, and near the pulley C, is rigidly fastened the pulleyJ, which, being connected to couutershaft H, by belt 6 and pulley I,imparts n10- tion to the same.

At the outer end of the conntershaft H there is att-ached a properpulley, giving motion and same dimandrel 1),' midway between tnefeedrolle1s E and F, and in position to saw the bolt or plank as itpasses through by the feed-rollers heretofore described.

The rollers E and F are provided with separatingcollars l, l, l,dividing the laths after being sawed,

- and securing a parallel position ofthe same until the laths pass fromthe Vsaws and rollers, and are delivered upon the inclined way U, andare deposited back of the machine, as may be desired.

It is a bar upon the top of the way U, which divides the lath. from thebolt or plank, the lath being disposed of, as hereinbet'ore described,while the `bolt or4 plank falls upon rollers L, when, by their motion,the bolt or plank is returned to the operator, the rollers P and P2Motion is given to the rollers L by p'ulleys 2, belt 7, and pulley 3, oncountershaft H.

The curved spring M rests at each end on boxes pivoted on top oftheshafts ll, near the yoke 0, and is secured at its centre by the screw Xpassing through a proper ear attached to the yoke O, thereby securing anadj nstability to the upper feed-rollers, according to the thickness ofthe bolt to be sawed.

'l is a platform or table, froln which to feed the machine, and attachedthereto is the wall S, acting as a guide.

V are stops at the ends of the machine, to prevent the bolts from beingdriven out of the ends ofthe machine, and suplmrting-bar Q serves for abridge-tree to sustain the outer ends of the rollers L and P, whiletheir opposite ends are sustained by the frame.

5, 4, and 9, are intermediate tightening-pulleys for the differentbelts.

\Vhat I claim as my invention, and desire to secure by Letters Patent,is-

The feed-rollers E, constructed as described, when-v used for thepurpose ot' separating the laths, as set forth.

JOHN S. HYDE.
